I wonder if we could unref the BufferData by removing it form the osg::Image and let it's ref count control it's destruction, and when it destructs it'll destruct the PixelBufferObject if it no longer has any references. This would be a bit similar to the way that the osg::Image is unref'd. Like this mechanism we'd need to make sure that the BufferData is applied to all the contexts that require it. Robert.
